Propylene graft copolymers

Propylene copolymers grafted with alpha , beta -ethylenically unsaturated carboxylic acid or carboxylic acid derivatives and consisting of a random propylene copolymer (I) with from 0.1 to 15% by weight of polymerized C2-C10-alk-1-enes and a random propylene copolymer (II) with from 15 to 80% by wei...

Beschreibung
Zusammenfassung:	Propylene copolymers grafted with alpha , beta -ethylenically unsaturated carboxylic acid or carboxylic acid derivatives and consisting of a random propylene copolymer (I) with from 0.1 to 15% by weight of polymerized C2-C10-alk-1-enes and a random propylene copolymer (II) with from 15 to 80% by weight of polymerized C2-C10-alk-1-enes, are obtainable by reacting the graft monomer with the propylene copolymer at from 1 to 300 bar, from 0.01 to 1.0% by weight, based on the propylene copolymer, of the graft monomer being mixed with the molten propylene copolymer in the absence of a free radical initiator, and the grafting reaction being carried out at from 200 DEG to 350 DEG C.
